BACKGROUND Significantly higher prevalence of Strongyloides stercoralis has been reported in chronic alcoholic patients. The aim of this investigation was to report the prevalence of Strongyloides larvae in stools of chronic alcoholic patients with known daily ethanol intake. METHODS From January 2001 through December 2003 the results of fecal examinations and the daily ethanol intake were re...

The course of Strongyloides stercoralis infection is usually asymptomatic with a low discharge of rhabditoid larva in feces. However, the deleterious effects of alcohol consumption seem to enhance the susceptibility to infection, as shown by a fivefold higher strongyloidiasis frequency in alcoholics than in nonalcoholics. Moreover, the association between S. stercoralis infection and alcoholism...

We report an atypical occurrence of invasive Strongyloides stercoralis infection of the stomach mucosa in an elderly female patient from Bangka Island, northwestern Indonesia. The patient presented with severe epigastric pain, edema of the legs, proteinuria and severe hypoalbuminemia. Gastric and duodenal biopsies found eggs, larval and adult forms present in the superficial mucosa with mild in...

The mortality in Strongyloides hyperinfection syndrome (SHS) is alarmingly high. This is particularly common in bone marrow, renal, and other solid organ transplant (SOT) patients, where figures may reach up to 50-85%. Immunosuppressives, principally corticosteroids, are the primary triggering factor. In general, the clinical features of Strongyloides stercoralis hyperinfection are nonspecific;...

Infection of a dog with Strongyloides stercoralis filariform larvae resulted in a persistent infection. Patent infections were not seen in rabbits, guinea-pigs, rats and 11 inbred strains and one outbred strain of mice. Manipulation of factors known to influence S. ratti infections in mice, such as age and sex of the host and the route of larval presentation, did not facilitate the appearance o...

Strongyloides stercoralis (SS) is a unique nematode with an auto infective cycle, so that it completes its life cycle within the human host and can live there for many years. In immunocompromised patients, infection can cause Strongyloides hyperinfection syndrome (S.H.S) that is associated with serious morbidity and mortality. As various infections are one of the leading causes of membranoproli...

The prevalence of schistosomiasis and strongyloidiasis among Brazilian immigrants in the United States is unknown. We performed a retrospective chart review of serologic screening of asymptomatic Brazilian immigrants during routine physicals. Of 208 eligible patients, 189 were screened: 27.7% (n = 52) had elevated Schistosoma antibodies and 5.8% (n = 11) had elevated Strongyloides stercoralis a...

The quantitative formalin ethyl acetate concentration technique (QFEC) was compared to agar plate culture (APC) for the detection of Strongyloides stercoralis larvae. QFEC could substitute for APC only when the parasite load was higher than 50 larvae per g of stool. This study serves as a good reminder to those conducting stool exams about the sensitivity and specificity limitations of both tec...

We report a case of autoinfection due to Strongyloides stercoralis in a 27-year-old Ethiopian AIDS patient living in Germany for nearly 3 years. This case was diagnosed on the basis of a single-view field in microscopy of a freshly obtained formalin-fixed stool specimen showing both rhabditiform and filariform larvae. The diagnosis of autoinfection by microscopy is discussed in detail.
